These fenders were the best ones the pro shop had there. They were $50! They seem to have cured themselves though, I no longer have fender vibration, and I didn't do anything. lol. So I guess it's all good. I keep checking all the fasteners, nothin's coming loose. I'm curious how the vibs stopped, but oh well I guess! lol, my bike doesn't vibrate much, so I don't think I have to worry too much. I'll always check them though. I routinely check everything now, since I have alot to inspect. lol. Thanks to everyone for your help!
